• When exposed to oxygen in the air, the iron filings inside the pouch begin to oxidize creating a rapid rusting process which in turn produces residual heat. Salt acts as a catalyst, while carbon helps to evenly disperse the heat. Vermiculite acts as an insulator that helps prevent the heat from dissipating too quickly.
